In 1985, 70 pct of the world's supply of phosphate is expected to be produced by the current leaders: the United States, the U.S.S.R., and Morocco. Phosphate rock production in 1985 is forecast to be nearly 219 million metric tons, or 71.2 million tons of p2o5, approximately double the 1974 production. A conservative estimate of present world reserves is 21 billion tons of p2o5, of which the amount remaining in 1985 is expected to be nearly 300 years supply at the forecast demand rate for 1985. Additional reserve discoveries are anticipated. The same rank in exports is foreseen in 1980 and 1985 as now: (1) Morocco, (2) the United States, and (3) the U.S.S.R. North Africa will become increasingly dominant in exports. By 1985 over 93 million tons of phosphate rock is expected to be involved in international trade; 52 million tons from North African and adjacent Middle East countries, 20.8 million tons from the United States, and 9.9 million tons from the U.S.S.R. Data on transportation costs, pricing, and production cost estimates are included; also maps and notes for the principal producing countries.
